2 Clams. (Cl. 189-53) My invention relates to hinged doors for stores,ofiice building entrances and the like, and more particularly to doorsmade up of 'glass panels in extruded metallic frames.

It is a purpose of my invention to provide to strengthen andstructurally simplify the frames for hinged doors with glass panels, soas to not only reduce the cost of manufacture thereof, but to minimizethe mode of assembly of the parts of a door frame in relation to eachother and to the'glass panel which it contains, and while 'effectivelysecuring the panel therein, also allows ready removal thereof should itbecome broken to substitute a new panel.

It is also a purpose of my invention to provide a door frame including asectional rail, which affords means for mounting on one of its Verticaledges hinges by which the door is hung in a doorway, and ,a second railon its other Vertical edge which is detachable to allow rails ofdifferent forms to heV used depending uponl whether the door is hung toswing in one or two directions, and whether it is hung from one verticaledge, or hingedly mounted on the floor to swing in both directions foruse in conjunction with a similarly mounted door to provide a two doorControlled entrance for stores and the like.

I will describe only two forms of doors, and various forms of jambrails, each embodying my invention, and will then point out the novelfeatures thereof in claims.

In the accompanying drawings:

Fig. 2 is an'enlarged fragmentary elevational view of the upper righthand corne1` of the door shown in Fig. l.

Fig. 3 is an enlarged sectional view taken on the line 3-3 of Fig. 1.

Fig. 4 is a sectional view taken on the line 4-4 of Fig. 2.

Fig. 5 is a view similar to Fig. 1 showing another form of doorembodying my invention.

Fig. `6 is an enlarged fragmentary elevational view of the door shown inFig. 5.

Fig. 7 is a transverse sectional view taken on the line 1-1 of Fig. 6.

Fig. 8 is a fragmentary horizontal sectional view showing my inventionembodied in a pair of doors mounted to swing to open position in one andthe same direction.

Having specific reference to Figs. l to 4`,;my invention in thisembodiment comprises a door D composed of a glass panel P in an extrudedmetal frame of .rectangular form and designated generally at F.V Thedoor D is of that type which is hung from one Vertical edge in a doorwayW by hinges H and to swing to open position in one 'direction only.

The door frame F is composed of top and bottom or end Sections [5 andIB, and side or vertical sections ll' and' l'8, and all sections are ofidentical construction. I-Ience, a description of the structure of onesection will sufilce for all. Each frame section as aforesaid is ofextruded metal construction,`preferably aluminum, and so made as to forman elongated body IS of hollow rectangular form in cross-section. Theinner end wall 20 of the section is relatively thick, and its outer sideis formed with a- Vdove-tail groove 2| adjacent one side of the section,which is coextensive in length with the section. Adjacent the other'sideof the section the wall 20 is formed with a' right-angled groove 22 inspaced parallelism to the groove 2| and likewise coextensive in lengthwith' the wall 20. The other end wall 23 of each frame section is formedon its outer side with a dove-tail groove 24 which is made as wide asthe section will permit, and coextensive in length with the section.

A pair of retaining strips S and SI, likewise o'f extruded metal, arecarried by the wall 2D of each frame section, and the strips of all ofthe Sections coact to secure the panel P within the frame F. The strip Smay comprise a fiat portion 25 of a width to span the entrance edge ofthe groove 2|, and this portion is formed on its outer face with adoVe-tail tongue 26 coextensive in length With the strip and insertableinto the groove 2| at either end of the section. The strip S includesalso a second portion 21 divergent in relation to the portion 25 andterminating at its free longitudinal edge in. an angular lip 28coextensive in length therewith.

The strip SI is of similar construction to that of the strip S. VVItsportion 21a is divergent to the flat portion 25a, and the'lip 28a isparallel to the lip 28 of the strip S. The tongue 26a on the portion25a,'a1though doVe-tailed and of the. same dimensions as the tongue 26,is readily insertable laterallyinto and removable from the groove 22because it is of right-angle form and of a width to accommodate thetongue.

This construction allows the strip SI to be mounted on theframe sectionby moving it laterally against the, section whichis in contradistinctionto the stripl S which requires it to be mounted endwise on the framesection because of the dove-tail form' of the groove 2|. With the twostrips mounted on the frame section they coact to form a fan-tailchannel 29, the lips 28 and 28a being spaced to accommodate therebetweenone marginal edge of the panel P, and the panel edgesecured' inVpositionby filling -thel channel With putty, cement or, anyothersuitable material 30 (see Fig. 3).

The strip SI, ,onceV applied as described, mayextended 3 provided andsecured in place and the channel 29 filled with putty with retainingstrips S and SI, it will be clear that all four edges of the panel P arefiXedly secured to the frame sections to form a complete door. Inasmuchas the strips SI are detachable from the frame sections by firstremoving the screws 3| and then loosening the putty, the panel can beeasily removed from the frame without disturbing the strips S, to permitsubstitution of another panel should it become cracked or broken.

To secure the Sections of the frame F in rectangular form prior toplacing the panel P therein, conventional tie-bolts B are extendectlongitudinally through the top and bottom sections 15 and IG, `with theends of each bolt passing through plates 22 fitted in the opposite endsof the frame Sections. As shown in Fig. 4 each plate is formed on oneface with a dove-tail tongue 33 and a right-angled tongue 34, thesetongues corresponding to the tongues 26 and 26a of the retaining stripsS and SI, and, hence, are extendable into the grooves 2| and 22. Thusthe tongue 33 serves to hold the plate 32 on the frame section 11, butto secure the plate to the frame section andagainst possible twisting ofvthe sections 15 and H relatively, the tie-bolt B is eX- tendedthroughthe plate and the nut 35 screwed home on the bolt. With suchconnections at all four corners of the frame, it is manifest that theframe Sections once assembled provide a non-twistable or otherwisedistortable frame.

The groove 2d in the Vertical frame section I'I receives endwise a pairof ribs which coact to form a dove-tail tongue 36 on one face of a railR for securing the vlatter to the edge of the frame section. It is uponthis frame edge that the door D is hung by the hinges H, the latterbeing constructed to allow the door to swing only outwardly of thedoorway. The hinges are secured directly to the frame section l'l byscrews 37 threaded in the wall 23, and to permit this the rail R is madein Sections With one leaf of the hinges between the Sections andabutting the ends thereof so that the latter aid in supporting theleaves on the door frame. The other leaf 38 of each hinge is. screwed tothe adjacent jamb 39 of the doorway, and thusthe door is hung in thedoorway.

The groove 24 lin therframev section IB receives lengthwise a pair ofribs 49 which coact to form a dove-tail tongue on the inner side of arail RI. Thisrail, as well as the rail R, mayI be termed a jamb rail inthat it faoes the other jamb 4| of the doorway. The rail RI ymay' bemade of any contour on its outer side depending upon the cross-sectionalcontour of the jamb 4|. As the jamb vis beveled transversely the side ofthe R1 is likewise beveled.

Referring now to Figs. 5, 6, and 7, I have here shown a door DI which ismounted on the floor 42 and the upper joint' 43 of a doorway WI to astore or the like, by conventional hinges I-Il to swing inwardly andoutwardly through the doorway. While the construction of the door frameFI thereof is Substantially the same as the frame F, the frame Sections[5a and 11a at their meeting ends are constructed to accommodate certainconventional parts of the hinges HI by which the latter can be adjustedto fit the floor and jamb parts of the hinge to properly mount the doorin the doorway.

Where the door DI is mounted in the manner described the railsV R2carried by the Vertical and Ho of thetwo door frames are provided withrails R3 and R4, the confronting sides '15 and 46 ofwhich are beveledtransversely, and one Vertical edge of the rail R4 is formed with anastragal 41 to span the joint between the rails when the doors areclosed.

This as well as the other forms of rails, illustrates the versatility ofmy door frame construction in its adaptation to single or double doors,and irrespective of the manner in which they are hung.

Although I have herein shown and described only two forms of doors andvarious forms of jamb rails, each embodying my invention, it is to beunderstood that various changes and modifioations may be made thereinwithout departing from the spirit of my invention and the Spirit andscope of the appended claims.

I claim:
